UNITED) S A E PAT T: jomcE i i The present invention 1 relates to steam" In the practice of the present invention,

locomotives, and more particularly A to improved means for delivering steam, frornthe boiler, to the orking cylinders of a locomo+ tive.

Heretoi'ore, in locomotives embodying at least two high pressure Working f cylinders, the steam has been delivered from the boiler to thevvorking cylindersby means of branch pipes, each leading through the smoke box,

one for the left hand Working cylin der, and

another for the right hand working cylinv H phand valve chest, and disposed outside of the der. In oneIWell-knoyvn typeof-c'onstruc tion, the branchpipes are connected to suit able outlets in the superheater, While, inanother well-known type of construction, in-

which the throttle valve is disposed forwardly of the superheatenjthe brainchpipes are connected to 1 suitable outlets in the throttle An objcctjof the present invention is to provide animproved form of construction whereby a material reduction in the amount of piping and'the number of pipe joints is effected,with a consequent substantial reduclion in the weight of the locomotive, and a greater efliciency of forced draft. 7 Another object, 'is to provide "a construction requiringbut a single opening through the, smoke :box for steam piping. furtherobject is to decrease to a minimum the volume of the steam passage between the throttle valve and the cylinders. 1 Another object, is to provide a si npleig'more compact, and more durable construction, whereby a substantial economy in installation and maintenance costs is effected, and greater efliciencv in operation is assured. Other ob In the accompanying draWingsFigure is a side elevation, partly in section, of the forward end of a locomotive embodying my invention; and, F g. 2, a transverse,' ,vertical section, taken on the line A A, Fig. looking in the clirectionoi the arrows.

inders, 13, a distribution valve chest, lg'for each Working cylinder, and a piston valve,

15, in each distribution valve chest. I l' c 7 A single throttle valve, 16, for controlling the admission of steam; to both of the dis tribution valve chests is mounted on the right smoke box and outside of the adjacent side frame member 11.

right hand distribution valve chest, to the left hand distributionvalve chest, for supplying steam to the latter; I a

In the construction illustrated in the drawings, each of the Working cylinders, its companion distribution valve chest, and one half of the cylinder s'addleQI'are formed as a single or integral casting. The steam pas sageway, 20 ,is formed jin'the'jinteg'ral castings,'being so disposed as :to pass through the cylinder saddle, 'It is'tofbeunderst'ood that the'working' cylinders, distribution valve chests, cylinder saddle, and the steam i'pras- 'sagevvay may be integral or formed in,vari-,-

ous other Ways, as desired, and that the steam passageway, 20, maybe an'independent pipe disposed outside of the smoke box and leading from one distribution valve chest to the other, or from a position in the passageway for supplying steam to the distribution valve on one side of the locomotive to a distribution valve disposed in a different vertical plane.

It is also to be particularly noted that the invention has application to any type of locomotive embodying two or more high pressure working cylinders. p

It is; further to be noted that instead of locating the throttle valve adjacent oneof the distribution valve chests, it may be dis posed adjacent the superheate'r, in the-superheater, in the steam dome of the locomotive,

or otherwise, asdesired. The casing of the throttle valve may be madev lntegral with the cylinder and distribution valve chest.

, One of the important novel features of the present invention is the provision of a single steamsupply pipe passing through the sm'oke box wall, for supplying steam to two ormore high pressure cylinders, whereby the number of openings required in thesmoke boxwall is reduced toa minimum. Another novel feature of the-invention isthe substantial reduction in the amount of piping i and the number of pipe joints, required to "iii conduct the supply oi steam for two or more high pressure working cylinders, whereby a material'reduction in the weight of the locomotiveis eilectechfland greater efficiency of forced draftassured. A further novel feature of. the invention is the reduction to a minimumiof the volume of the steam passageway between the throttle valve and the working cylinders; A further novelfeature of the invention is the formation in the cylinder saddles of the steam supply passageway from one high pressure cylinder to another. Another novel feature of the invention is the placing of the throttle valve at a. posi tion where it is, conveniently accessible for lnspect-ion and repair. A further novel featureof 'theinvent1on is the plac ng of the throttle valve, its operating mechanism, and ,the steam supply pipe, on the opposite side of the locomotive from the air compressors, feed water heater pumps, and other accessories, whereby the weight of such accessories is counterbalanced W here the two cylinders are made identical the opening on. one side is used for the steam inlet from the throttle valve and the opening on the other side may be used for a conpassageway, passing through the smoke box 1 wall, and adapted to conduct through said ing through the smoke box wall, andadapted to conduct through said ,wall, a suppl of boiler steam for at least two ofthe wor ing cylinders, said passageway leading to one of the distribution valve chests, a throttle valve in saidpassageway disposed outside of the smoke box and at a positionito one side of the longitudinal central vertical plane'thereof permitting unobstructed access for inspection and repair, a second passageway, communicating with the first passageway at the delivery side of said throttle valve, and communicating with anotherotsaid distributionvalve chests. y
